The book ‘Outliers’ by Malcolm Gladwell talks about the 10,000-hour theory–that almost anyone can master a skill if they dedicate 10,000 hours to it. The same is true for your side hustle. If you put in the right hours–into the right places–then you can build a successful side hustle, too.The rate at which you put these hours in is up to you. Yes, if you go slower, then it will take longer. But compared to your other option–doing nothing at all–what’s the hurry?Here’s the tried and true technique I use to put the necessary time into any new project without overwhelming myself:Set aside 20 minutes–no more!–every single day to work on your project, and protect those 20 minutes with everything you have. Never let anything get in the way of this time.
