You may be the average of the five people you spend the most time with , but more so, today, you are the product of who you were yesterday and the day before . “The difference between who you are now and who you were five years ago is largely due to how you’ve spent your time along the way.” 
So, who are you seeking to become?
If you like who you are today, keep doing what you are doing. But if you want to change, work to retool the habits which defined you up until this point. You don’t have to appease social norms of being the same person you were yesterday. Buck the tread and become who you want to be. (Do you believe people can change? ) Fight club and Tyler Durden show that resetting can be the impetus for your new, desired self to take hold. You don’t have to set fire to all your possessions, but find what brings joy to your life  . Don’t let your possessions own you . “If you can’t afford to lose it, you can’t afford it to buy it yet” . So as spring rolls around here in the US, what cleaning will you be find? How will you shed your skin to let your new self shine?
