If you feel called to do something, then removing the barriers stopping you should be one of your biggest priorities.
If money is the problem, mastering money is part of the solution. Read every insightful book on money you can get your hands on. Apply what you learn. Live below your means, while also increasing your means.
You might find that money was a problem but was masking the real barrier (such as fear). That’s good. Now you know. Now you can master this one as well. Keep going down the list until there are zero barriers/excuses left.
