Iam only going to tweak the first few sentences:

Simple Steps!

Life is an odd thing, it is so complex, but people handle it very well JUST by doing small, and simple things!

They put We have rules for everything, even for having better improving our relationships!  they give you some guidance rules!

Everything is teachable CAN BE TAUGHT, even from painting, TO playing football, loving, and even caring.

 isn’t it odd? (PROB OK for spoken English, but in writing, prob better to have: ISN't THAT odd?  For you maybe not, but for me it is somehow shocking really.

It just confuses me a lot! You should just learn simple rules and then start! How much odd! :OOO! I have always thought since things are complicated, they require complicated acts to be done. (<--- NOT SURE WHAT YOU MEAN)

 Buying a red rose for someone is simple but the effect which it would make is so complicated! :O
It just surprises me to see how simple things can greatly affect very complex things! I suppose if I eventually could convince myself to accept this fact that all I have to do is taking some small and simple steps, I would eventually get moving!

If you ask me what the hardest thing in the world is?
I would tell you, teaching yourself is the hardest job in the world. Actually compelling yourself to do things is really hard. I have lots of things to do but I wasted all my day today, I couldn’t compel myself to sit and start doing them. They say I could have not wasted my day today, if I had set some goals for myself, and put some deadlines to do them! Odd, but they say it would work.

I hope I can eventually persuade myself to believe that I can manage things by taking some simple steps! I am trying to teach myself step by step!
