Over the last number of years Ive removed things from my life, all for the positive
Less light: Use candles, theyre tantalisingly peaceful
Less negative people: At times unfortunate for those that you leave behind, but a brilliant gain for you
Less sugar: Not hard to wean off of across the board, with nice health benefits
Less driving: Easily boosts general calmness
Less ad-hoc planning: Bigger picture planning minimises the need for less-effective on-the-fly planning
Less worry: Its excellent how switching out a negative thought for a positive one brings a greater peace
Less smoking: So Ive not smoked before, but have seen good positive change in people that have quit
Less TV: Filling those hours with other desirable pursuits is relatively easy and so much more satisfying
As always, developing any habit (good or bad) takes practice, but with persistence and grit you can successfully get whatever you want (whether it be more or less)
