In 6 months time, when you haven't started, you will be in exactly the same place as you are now, except 6 months into the future. If you start today, in 6 months time all the things you think you're bad at now, you will be better at. So would you rather wait 6 months to still be as bad as you are right now? Or would you rather spend the next 6 months giving it a go, refining your skills, trying things, and getting the data that will help you to tweak and grow?
