I guess it depends on your life situation most of all. You're married, have kids, serious job, etc...
Then it's only your thing how you stack up the priorities. Of course, family and a job that makes your living should be way ahead of chasing at any situation.
Depending on where you live I guess it is not a bad thing to chase as much as you can during May or June. If you chase plenty during these months, good for you. You can do whatever else you need/want during the rest of the year. Remember all the crying here on ST during winter months about people not being able to chase... May is not here yet... it should get busy soon. During those several weeks go out and give it your best. Nothing wrong with that, again.
I want to do what makes me happy. Yes, if you have responsibilities, go ahead, don't let chasing stop you by any means. There will always be more tornadoes... It is up to only you to do what really makes YOU happy. You are free to do whatever you want while you're here for a few more years...
In Florida Keys during summer months it gets really "tough" in a possitive way. Any given day has not enough hours for me to sleep and chase. Yeah, the life is laid back, job pays well and wife is very understanding... so I chase a lot. But it is MY life situation. I don't really feel like missing out on anything else when chasing. There is always time for other things.
And there is always plenty of days with no storms and me wishing there was one.
I scuba dive a lot ...also go boating, fishing, go on trips abroad, go to malls, party with friends... but nothing makes me happier than seeing a good storm, hearing thunder or seeing some serious lightning activity no matter where I am or what the heck else I am doing.
Me and my wife love to go hang out in Key West. Great Irish pubs there. So we are sitting there one afternoon, sipping on some Strongbows... sky gets darker... I grab a camcorder, run to Mallory Square, shoot a quick footage of a great waterspout and casually come back...my wife and a bartender smiling... no stress, taking it easy...not pushing anything...relaxed. Why are people stressing out so much about chasing or during chasing !? What is at stake you might wanna ask yourself... money spent ? What else are you saving those for.... retirement... to be able to chase when you are 70 ?
Yeah I know.. the long driving gets very boring sometimes...
Anyway, during summer months I get back from work before midnight and it is usually lightning somewhere nearby, pretty much on a nightly basis. So I grab my equipment and go shoot lightning over the ocean or Everglades, many times till sunrise.. best shots usually come just before sunrise...well, then it is a nice time for early morning waterspout activity... we usually get some good ones during the early am hours. As the day heats up, storms pop everywhere, along with cloud lines that produce waterspouts. So you could be up all day, chasing. Very nice ! And so the cycle goes every day between May and November. Throw in some active hurricane season, severe weather potential during early spring and a trip to the Plains in May/June... I just really enjoy it. I also don't think it helps things when you do it for money reasons...more stress...
What ever you do, you should really feel relaxed about things, otherwise you are never gonna enjoy it...
So, to answer the question - yes, I choose to chase pretty much every time since I feel there is always more than enough opportunities to do "normal" things during other times.
All in all, I could never put it here in words better that Shane did above.
