Do not be surprised at this!
Your dreams are huge. New people and ideas keep coming. New projects start. You are changing. Your life is changing. Your body is changing. Those you work with are changing. All along the way you will discover new things about yourself, your energy levels, what inspires, what drains. There will be a continuing need to re-examine and then adjust, based on the new understanding that you have.
Do not be discouraged at this need for continual discovery and change. Do not give in to the misplaced idea that because you have not yet "figured it out," somehow you have failed.
What will work for you, will not work for someone else. What works for them, probably wouldn't work for you. YES! Learn from others. YES! Adopt and adapt time-tested principles. YES! Take on their wisdom and use it in your own life. But you are not "them" (whoever "they" are), and "they" are not you.
Lay down this idea that "getting it right" or finally "figuring it out" should somehow be your goal, or that it is even possible. Drop the all-or-nothing thinking that leads you to either focus on "figuring it out" or giving up via the many ways you can run.
Know that you are loved, you are valuable, what you do matters, and this all while you are so NOT "figured out."
Learn to live each day in hope. Learn to live each day, each moment, making the wise choice for that time. Yes, keep setting aside those times to stop and evaluate and strategize to make the adjustments needed based on what you see now. But do not expect it to be perfect. Don't even hope for that. Realize and embrace the reality that even the new (better) plan will need to flex, change, and someday it may be scrapped altogether. It will serve your journey for the time it was needed, and that is enough.
Again, take a deep breath.
Life is good.
Live it exuberantly.
Live it well.
In all your glorious, imperfect messiness.
