Waiting for a better day?

Today is as good a day as any to do what you’ve been

 wanting to do.

There's no need to wait for a better day.

Yes, a better day may be preferable, but is not necessary. 

Work with what you've got until you get something better.

If you work miracles during a bad day, imagine what you

 can do during a good one.  #TheCubanGuy
