My thoughts on advice for those just starting in their careers. Reposting this response I wrote because I thought it was useful.
You have to hold these two concepts in tension. First, assume you will be aggressively working your tail off at first whatever you do. There will be a lot of gruntwork and learning the ropes. This will pay the bills, establish a basic skillset in your field and make you useful. This is the first step. It takes 40-80 hours per week.
The ultimate goal is to be an owner, not an employee, at whatever you do. Here you have ups and downs (risk) but always better to be an owner than an employee. You have more freedom and control over how you spend your time here. This is where you have something that makes you money with 4 hours a day. Even if working a 9-5 6-figure job, you need to have a second “night job”. This can be related to your “day job.” E.g., if you are a lawyer or accountant or banker, use 5pm-10pm to build your network, business, practice, prospects, write, speak, grow. It doesn’t have to be related to your “day job.” It can be chasing your obsession until it becomes economically viable.
As a wise man once told me, if an effort level of “100%” (arbitrary number) gets you 100% of your desired outcome or goal, 90% effort will not get you 90% of the results. It will get you 0% of the results. You have to redline (at least initially) until you get the flywheel moving. Once you build momentum, it is easier to maintain (but still takes discipline to remain consistent in the efforts).
