I know the feeling. I too have failed miserably over and over again.

I could tell you like the others you haven't failed or your not a failure but the point is you feel that way.

But I can tell you this. One trait all successful people is they regard failure as a setback not a failure. Yes the old cliche learn from your mistakes really is true,

So keep getting back on the horse kid and never ever give in to the perceived failure. Hey for most of us life is 1 step forward and 2 steps back so why worry about it.

Or here is another visual I make for myself:

Imagine you are in a row boat that was headed toward Niagara Falls. So you realize what is ahead of you and you start paddling like there is no tomorrow to stop from getting any closer to going over the falls!

Maybe a "normal" person figuratively could pull themselves out harms way while those of us who struggle are hampered and may only be able to stay in the same place.

Hey the reality is you are accomplishing something! You are maintaining a safe distance and at least keeping yourself afloat! Don't trivialize that, it means more than you realize.

Many before you and many after you will simply give up but not YOU!
