Have You "Made It" Yet? If Not, Do This
As humans, we're wired to continually grow and become better versions of ourselves. I don't know how or why, but you just feel bad when you stay in the same place or aren't working towards a better future.
What do you need to get yourself to that point where you want to be? 2 things.
Have a long-term vision of what you really want from life. Nobody can tell you what you want except yourself. Want a Ferrari? Great. Create your long-term vision and add a Ferrari in. Do you simply want your own company and to live life on your terms? There you go, your vision is coming together.
Make actionable steps to get you moving towards your vision. Believe in yourself and keep improving every day. Set aside $200 a month in an ETF account and who knows, by age 45 you may just have that Ferrari ;)
