How can I stop being a pushover?

Start to say no. For little things, very nicely "Oh thank you, that looks delicious, but I'd rather not have another cookie, I'm feeling full." Learn to say no without saying no. Learn to stop saying I'm sorry. Rather than apologizing for being late you could thank people for their patientce. They'll feel better and you won't always hear yourself say sorry. Over time learning to stop saying I'm sorry for mundane things and learning to say no can build a part of your confidence. Your voice, your opinion, you matter!

yes. One needs to have more confidence and control of your surroundings. Learn to build your self confidence in things you are familiar with.

Learn to say no. For some reason a lot of us are afraid to tell people no when it comes to things we don't want to do. We need to change that.

I have personally found that willpower is the key to that question. In my opinion, you must learn how to become more cognizant about all the factors in every situation, and push yourself to the maximum. Refuse to be inferior in anything you do from the bottom of your heart, but do not let your ego grow too large in the process. That is my two cents.

Take a stand, give insight and opinion, don't sit with a closed mouth and a passive attitude; be more outgoing, personable, social, and in tune with your internal desires; share your internal emotions, strengths, and overall personality in an effort to communicate the best, most admirable side of you; don't settle for other people's judgments, conclusions or assumptions; build yourself up and project your own set of values; take it slow and steady.

The starting point is first to find what you believe in . Often deciding what you want to do / to become /is the hardest part. Knowing what you want is linked to a strong sense of self identity. Try to become more self aware. After subsequently finding out what you want you can work on asserting that. You need to ask yourself why you allowing yourself to be a pushover? - is it due to lack of self importance ? The view / perception you have of the other individual? or is it through lack of communication assertiveness? Upon finding your inner self , stand by them , assert them and fully believe in them. Self belief and confidence will allow people to take onboard your input and view you as an assertive person.
