Rule of the life
If you have to do something, first, think about consequences that can came from your deeds. Now, this is very important: if the consequences of a deed are good, then also a deed is good,and when a consequence is bad, then also a deed is bad. It's simple to understand that.Following this rule in your life, you can have mistakes in your life on a minimum level.
Also, you can take adventage, sometimes,on what will happen. :D
It's a good feeling only to do what you can do, and what is OK.
I must say here, every person have a chance for changing things in life, the problem is only how we understand that. If you want a change in your life, things going better and so,follow this rule, and believe in yourself. I give you this rule for free, but it's very valuable. ;)
