Ok, I’ve hit a milestone, so now what?

I recently hit a milestone in my life that took me a few years to get to. As the new year approached, I was asking myself, ok, now what do I do? I believe we all reach this point in our lives at some point, whether we are aware of it or not.

After a little thought, I’ve come up with a few more questions (still working on the answers):

Do I increase my goal/milestone, and reach for it over the next year or more?
Do I work to maintain this current level
Do I work to maintain this current level, and work to increase quality
What items specifically got me to this milestone?
What do I need to do in order to not ‘back slide’
Assuming this milestone was in one area of life(work, family, finances, ect), did another area suffer as a result?
What is my next goal/milestone?

I don’t claim to be an expert in goal setting (or goal accomplishing), hence the abundance of questions rather than answers. But often a well phrased question is more productive than an eloquent answer from an ‘expert’:)
