So what

You will screw up anyway
You will repeat the same mistake anyway
You will face the same situation as you dad anyway
So why bother avoiding it or pretending not to have it

So what if you screw up
So what if you repeat the same mistake
So what if you faced the same situation as your dad

The one thing which you can only do, and you should do, is to move on
Move on
Easier said than done, but it's important

Look towards the future
Learn from the past
Even if it's too late to amend some things, you still look forward
Even if you know you're going to screw things up and learning lessons when it's too late, you still look forward, as if nothing has happened
