You can’t do it alone. You will have to stay up late. You will be laughed at and mocked. They won’t respect your intial purpose. You won’t have everyones support.
You will doubt your abilities from time to time. Some people will hate you. Others just won’t understand. You’ll be brought to tears at some point. Eventually you will want to quit.
Regardless, you need to hold your chin up high, count your blessings, and just keep working the plan, until the plan works.
