I'm giving up doubt

I'm giving up doubt
That's my task this year
I'm giving up putting myself down

I'm giving up doubt
Trying to overcome fear
It's too long been making me frown

I'm giving up doubt
"But how?" you might say
It'll definitely be a force of will

I'm giving up doubt
Starting from today
And here is what's on the bill:

I'll learn to run
I'll eat as my plan
I'll start forgiving myself

I'm giving up doubt
Do you want to try?
Why don't you challenge yourself!
