42 M - Thinking of selling high

I’ve been skeptical of the rocket ship growth/returns for at least a year+ (thankfully I mostly held in), but I’m at a point with my main brokerage holdings up between 80% - 200% (glad I bought Intel near the bottom!!)

Obviously this growth may continue, but feel like taking some strong earnings and move into SCHD or similar funds.

For some context:

$285k combined income (I make 90%) as my wife is working to scaled her Diabetes/Nutrition business)

$140K left on mortgage (2.37%) - only debt

Retirement accounts at about $700k

College 529 for 10/7 year olds on track to cover a majority of school (thankfully family has helped)

Aging parents, could potentially inherit (not banking on or expecting ) $2-4M

Concerns: In a new role (over my skis and working 12-14 hrs + 8-10 hrs on weekend). Concerned I could just flame out or… fail
