Do you have passions and goals that you stick with for a long time? Do you tend to change direction and move on to new interests when you find something you like?
We set goals of all calibres for ourselves every single day. People with grit tend to succeed in achieving their goals, simply because they stick with them, through the good and the bad. What makes us formidable is the ability to always keep trying, even when we doubt ourselves.
Some of what will get you to the finish line might not feel exhilarating or satisfy at the time. It may be boring, tedious and really difficult.
There’s a reason you want to accomplish these things, so respect that desire and do something about it.
