The art and strategy behind the longevity of anything are having clear outcomes, then attaching it to the necessity or purpose in your life. We have a 2 and half year old daughter, Charlotte, our clear goal is for her love what she does, make friends and socialize, follow directions, be empathetic, respectful, and continue to make progress every day. This allows us to search for particular activities that meet our goals and needs for her. As she gets older and develops her emotional capacity further, we'll start to consider what she says she's interested — but being clear the specific values we what her to develop makes it easy to discover what to do.
When we attach our necessity or purpose around the clear values we want for her, this allows for extremely deliberate actions to be done. The necessity that drives us is being a close family and building a tightly knit community with friends and loved ones so we can create the family memories that will last forever and can be passed down through the generations. This makes our decision extremely clear and our ability to say "yes" to the thing that fits and "no" to the things that don't.
Also, understand that this is always changing because we enter different phases in our lives, so it's a constant activity that has clarity around your objectives and the necessity that drives you.
How does all of this pertain to golf...in every way you can imagine! Without finding clarity behind what you want to achieve, you'll always be putting tremendous effort in and not understand why you aren't getting closer to your goals. Without the necessity to drive you, you'll say "yes" to too many things that don't move the needle towards your success. Your ability to say "no" to almost everything and only "yes" to the few things that create the largest value is what is separating where you are right now from your next level.
