i can do it

I can do it . I know I can but something seems to be telling me I can't. but can I? can I? can I?
To this question, I dont have an answer to it. But, please my friend can you answer for me? Sorry, I can't answer it I can only tell you, you can . However, I can't tell to what extent you can do what you can (but I know you can), you'll have to answer by yourself.
So how far can you go?
Answer for yourself
You have only today, if it goes it becomes yesterday.
I want to hear your answer
