Make sure you balance between getting quick, easy wins and working to overcome a difficult challenge. Getting those quick wins can provide a boost to your energy, but if you only focus on the little wins, you won’t ever achieve the unrelated big wins, which are often going to take much longer and require more consistent effort.
The best way to win in each scenario is to tie the little wins to the big wins. What small project can you conquer that will act as a stepping stone to winning the bigger projects? If they are related, you can directly work on one project goal while indirectly bringing you closer to your other project goal(s). If the two projects are unrelated, you will have to make time to complete both projects.
