no matter what, you need to make the time for yourself. whether that is going to the gym, doing yoga, running, or sitting on the couch doing nothing, just schedule time for yourself.
Like everyone, we're all busy and there are innumerable activities that will take away from the things we "want to do". There's a thousand "need to do" items on everyone's list. But doing all the "need to do"s won't make a happy life.
I've owned one business for 3 years and am starting a second one as we speak. The first thing I learned when starting the first business is that you have to make time for things that are important.
For me, that's going to the gym. I just learned to tell everyone (family, friends, clients) that they cannot touch me between the 6 and 8 pm at night. I was off-limits and if they couldn't get to me before or after that time period, than it must not be that important. I learned that people actually respect that - and I've been clear that that is personal time so they know where I'm at.
The only person that can break that rule is someone I'm dating seriously - and then it has to be REALLY important.
