Go 'ALL-IN'
Find YOUR Purpose.
To do this, you need to find your passions in life.
You don't usually just stumble into your passions though.
You need to continually be experimenting with new skills and knowledge, but not lightly, not just for 'fun' or as a hobby, it needs to be done RIGOROUSLY.
Don't give up on that book or that new workout routine or that article you're writing.
Maybe it's your passion and maybe it's not but the time, effort and energy that goes into developing that new skill or knowledge will transition to somewhere else in your life or will reveal aspects in the tedium of it all which you can re-direct towards your passions in the future.
When you discover your true passions and go ALL-IN on them they will come together to make you the person you are meant to become, you will find your purpose through the strife.
I feel most people who are 'lost and confused' with their direction in life have SOOOO MUCH discovery to go. Most have been doing what they were told to do in life and have no clue what they are passionate about or they found 1 or 2 things they are passionate about and just 'dabble' with it. .
Go ALL IN. Do it for YOU! Do it because discovering your passions and your purpose in life will benefit others and the world. Do it because nothing else really matters. Do it because it's what you were meant to do...
