In most cases we set goals without having a real plan only because we think we're supposed to. It's the New Year and we heard we're supposed to set goals, so we don't but don't exactly know how.
We need to start with achievable goals first and build a sustainable plan that will last, instead of jumping in with two feet having no idea why or what we're doing.
Working together is important, even if you're used to doing these things on your own. There's a reason this hasn't worked in the past, most likely because you've tried to do it on your own.
Find a community, find a support group and you'll quickly find out how important it is.
Consider other goals as well. In most cases people only set wellness goals, but what about financial for example, what about adventure. Do something you're not used to, think outside the box and you'll be all the better for it!
