That was me and only me

{Oh myself, that was me and me myself!
Don't abandon me, look at yourself!
I've learned and took you one step forward to our new self!

I've used my past to protect you from the futures trap. You haven't reached Perfection and I'm here
to help. Treasure me, I'm your tourist.
No matter how the future puzzles you, I'm always ready to equip you with infinite weapon. As you develop, I eat each moment you spent.
You won't stop my progress even if you did the impossible. Only one key you can use to set me free.
That is you death!!

I am your enemy and so your partner!
You can win over me or lose, either by serving your soul to me or smile through thousands of tears in your eyes...
I can hurt as easy as you wish as you can climb me as simple as any ordinary ladder...

Keep me and I shall grant you wisdom and happiness!
Lock me in your heart and I shall keep your precious memories safe!
Come back to me anytime and I shall draw a smile to you!
Only if you use me well!!}
