Why do I dislike a job I once enjoyed?

There could be many reasons for this. Change of management, bigger or different work load, lack of progression, relationships with coworkers or feeling undervalued. You may simply be bored of the job and feel as of you need to move on to something different.

Everything we like have a certain life time then it gets old for us we are always in need of a change

I am sorry to hear that your job is not enjoyable for you. Perhaps you are no longer feeling challenged by duties? Have you considered taking on new responsibilities at your job to help you feel more fulfilled? I wish you the best of luck at your job and much happiness.

Why are you doing this job? Is it what you want to do or what u think u should do? This is an important question to ask yourself.

day to day life can become repetitive and you need to change things up to keep it interesting try take a holiday or some time off just to recharge and renew your drive when you return

Its called "burn out" That is why we take vacations, Or our tastes change, Or the changes that take place. This sort of thing is a natural response to boredom.

Because people change. It's against human nature to stay with one thing forever and ever. You're not the same person you were when you started your job and it's only natural that with time, your opinions start to change. Maybe you become bored. It's all understandable and perfectly normal.

It is totally normal to not enjoy things that you might have once loved. It might be because your perspective changed. Maybe your job includes more roles and/or responsibilities that it once did not include. Maybe the people that you work with have changed. There are literally so many different possibilities! It could also be something as simple as you. You could be growing as a person and might find your job not fulfilling your ability and/or drive. Something that might have taken you lots of time and energy, might be very easy for you given your experience in your job. The important thing is for you to find ways to make it exciting again, through new experiences, or move on.

Along with new acquainted professional skills our preference and enjoyment change too. It's only natural. You can evaluate why you stopped enjoying the job to figure out if you want to regain the excitement or if you should consider looking for new challenges workwise.

Your personal preferences can change over time. People are always changing and growing and that can lead to enjoying new things and not enjoying something you used to.

Two possible reasons; stagnation and complacence. Stagnation occurs when excitement wears off and you become dissatisfied with your general place in life. Complacency occurs when you start to get about the things you are grateful for and look for other things - it's human nature and very normal. In this case, you may need to step back and reassess what you love about your life, what's missing, and where you can go from here.

it can be vacause now you are a upgraded version of yourself, and as the way you think changes your world changes

Maybe things have changed - for example your schedule, the workload, the people you worked with or the environment of your work place. Some people get bored of their job and seek to find something new. Make a fresh start and find something else you may enjoy.

I would first try to look at what aspects do you believe is causing you to dislike your work. Once you are able to identify them, try to see how they can be adjusted.

It could be due to monotony or stress. Anything done with positive and clear mind will be enjoyed better. So try to be positive and stress free to enjoy the job again.

People's interests change, and that is completely normal. You are allowed to change your mind. So if you originally liked a job, maybe you don't like it now because your environment or personality changed.

It could be because of one bad experience that now makes you think negatively about everything you do at work. Try and figure out what that one thing was/is and see if you can make yourself enjoy it or even try to cut that part out completely

You may be experiencing the negative effects of the people who are around you, or you don't feel like your time is being used the best way it can be. You could have grown out of the job, or perhaps found that it did not turn out the way you had thought it would.

Sometimes we can lose interest, motivation in things we used to enjoy. Often this can be caused by emotions and feeling that we are going through. Sometimes we need to talk about how we are feeling in order to start enjoying these things again

Things change. Maybe you've grown as much as you could in your current job and your tasks seems redundant.
