Change is an inevitable constant, most dislike and reject.
Learning to embrace change (inner and outer) is critical to your progression and growth.
Nobody is ever who they once were...as such, reinvent yourself always into a better version than before...however you define that.
It took me a long time to relize that I was directly responsible for my success or lack thereof.
Decisions and choices in life impact beyond comprehension. At times in the immediate, more often than not, years later.
Most decisions, good or bad, usually manifest 4 to 5 yrs later...a statistical fact.
Being mindful and employing deliberate thought to decisions/choices can truly be life altering.
That said, it is NEVER too late to embark upon a new path... I wish you all happy and prosperous journeys...in all aspects of life.
