Generally, the majority of people who make New Year's resolutions end up bailing on their goal of self-improvement within weeks or months. This failure is a shame because a lot of people make announcements and proclamations on social media sites such as Facebook. It can often disappoint or even dissolution people if they see people on these sites ditching their resolutions.
Also, don't just say that you want to start going to the gym. It would help if you had a realistic, clear, specific goal, such as attending Pilates classes or running outside four times a week. If you can’t measure it, the resolution may not come to pass because vagueness and being timid do not often breed successful results.
