You need a big goal before a SMART goal.
Forget about the A in SMART goals. Forget about what is attainable. First, you should set a goal that excites you.
Why? Because you don’t know what is attainable. You haven’t put in the work yet to find out.
I hear all the time, “I could never…run 10 km, …do a pull-up, …hold a plank for a minute.” Don’t let self-limiting beliefs take hold. A 10 km run, a pull-up, holding a minute-long plank are attainable. Check out what changes this athlete has accomplished starting in his mid-eighties. Don’t assume you can’t.
There is a benefit to thinking big. It is exciting. Exploring what you never thought you could do might change your mind on what is possible.
Pick a goal that is life changing. Forget about what is attainable. Work on something that could change your life.
Think SMERT instead.
Once you have chosen your big goal, then you can break it down into small, attainable steps. But first, you need a big goal.
