...then life is hard and enjoying the processes of your life becomes problematic.
What are you trying to prove?

Not fun
When you're trying to prove something, you're doing that on top of the hidden belief that you're not that already.
Trying to prove it will reinforce that belief. And whatever you're trying prove will never be proven enough.
Consequently, you will never get to believe or feel that life is your playground and everyone is your playmate or potential playmate. Life will still be hard.
Unproving
You can let go (step by step) of trying to prove something by undoing the fear that you're not that.
The fears are:

...that you're not good enough

...that your life is not worthwhile

...that you're not a good guy

...that you're not smart enough

...that you're not lovable

...and so on
Use undoing fear with this sentence (exemplifying one particular fear), "Holy cats and jeepers creepers, I am so scared that I'm not good enough!" eleven times.
Or (with another particular fear), "Holy cats and jeepers creepers, I am so scared that I'm not improving."
What if there's nothing to prove?
