Some people believe that it’s better late than never. I would disagree. Delaying something until tomorrow can lead to push it off for days, weeks, months, year, or forever.
Instead of postponing something, I would suggest asking yourself if you are still interested in achieving that goal. If no, choose something else. If yes, start with something that is so small you can accomplish that step easily and set the stage for ongoing positive momentum.
Have a great day,
