Say stop to resolutions that soon turn into constraints!
To avoid bad habits coming back, don’t set objectives that are too ambitious.
Consider your resolutions as a positive challenge to make your life more enjoyable! It is useless aiming at changing all in once. Use a stop-by-step approach and set a list of priorities among your resolutions.
Start with simple things, like sorting your clothes and choose the ones you have not been using for the last two years (and give them away. This is a good practice according to the Feng shui). Then replace a bad habit with a good one, like drinking more green tea instead of coffee.
Be kind to yourself and indulge yourself from time to time. The goal is not to become more stressed but to love yourself.
