Dream big but not for too long!
You can find lots of articles about dreaming big, some positive, some negative. Dreaming big is fine and sometimes necessary.
BUT
The big dream is not enough. Just dreaming won't get you there.
Hard and persistent work will do.
So stop reading another article about dreaming, motivation, life hacks, time management, etc.
It is only an excuse for doing nothing.
Start DOING things.
