confidence

You are knowledgeable.

Whether it's in the traditional sense or from street experience, you know things.

This makes you important.

Your know-how and qualities are valuable. To your friends, family and all other beings that depend on you.

Which makes you loved.

People only devote their affections to those individuals who improve their day - something your awareness and expertise do frequently.

So, don't ever doubt yourself again.

Self-confidence is the feeling of trust in your own abilities, qualities and judgement. And you have all of those things.

You are knowledgeable.
You are important. 
And you are loved.

Don't ever forget that.
