Question

How can i change myself ?

Answer 1

Identify the problem. 

Do self-affirmations. 
Visualize your changed future.
Expect disruption.

Answer 2

Well, first of all, if you ever got a thought that you don't like yourself and are willing to change; I would say, ACCEPT. We have to accept ourselves before we take any further step towards change. And by ourselves, I mean our strengths and also our weaknesses. I would not call it 'change' because changing our selves completely is like shedding our character. So we should know that change is not what we want. What we want is to become a better version of ourselves; to become better than yesterday. So the following would be those steps that I would suggest for your betterment.
Step 1: Accept both strengths and weaknesses of yourself.Step 2: Acknowledge what you want to change.Step 3: Seek the Solution.Step 4: List down the exercises for achievement.Step 5: And finally, Begin.

Procrastination is a barrier on the path way to success. The only way to avoid it is to start working on your faults immediately.
Hope this will be helpful:)
