When you start an ambitious project you’re excited because of the journey that you’re embarking on. Months in, you’ll probably be cursing at yourself for taking on a project that’s so ambitious.
At those moments where you’re cursing yourself or feeling like you may have taken on something that’s too challenging, it’s helpful to have someone there to say “keep at it”! Whoever that may be, make sure you assign someone even if you don’t have a significant other to help you out. It could be one of your parents, a good friend, or anybody else.
Starting off with a long-term vision makes it way too easy to quit early on. Break up the project into chunks and then set reasonable goals. Eventually you’ll create your vision :)
