Being Busy - Theory Time

Now does being busy necessarily mean being happy. I know that for me being busy definately helps me to be happy with my situation than if I wasn't busy. Especially if I wasn't busy enough to take my mind off of annoying things. And does being happy mean that you are happy with the life you're living or that you love life in general.
I know of a lot of people who love life but aren't happy. Also, I know a few people who are really busy but aren't happy. So to be happy, what does one self have to do to achieve it.
Ok, here's an example.
I got married to the most amazing guy in the world and had an amazingly awesome marriage. But I wasn't entirely happy, not because of my husband but because I didn't feel like I had achieved much up to that point. I didn't have a career, I wasn't a homemaker, I wasn't crafty or anything, wasn't in any clubs and didn't have any achievements or goals. I felt like I was stuck in the same place.
At the moment, I am busy with my calling at church, going out a little bit more to socialise, writing a book, in a musical and I feel really happy. I feel like I'm actually achieving something great.
So if these two had been combined and happened at the exact same time, I think I would've been so euphoric. But it didn't happen at the same time did it.
I just got off the phone to a friend, who is in YSA who says that she's not happy with her life. She needs a change and being a YSA in Hamilton is too repetitive and boring. And that a couple other YSA are feeling the same too. So I wondered to myself. If I hadn't gotten married and had children, would I have been stuck in that vicious YSA cycle where you don't progress. where your life just goes around and around in circles and living from one paycheck to the other. With no goals but to socialise with each other. I think I would be really unhappy at the monotomus lifestyle.
I guess at the same time, I don't work so I've been treating my calling as a part time job. Now, because I'm the secretary in YW, I have made up templates for every single thing that is needed in YW. On Sunday, someone asked who the secretary for YW was, I turned to her and said that it was me. She just replied, Oh, I didn't realise. I thought you were a counsellor or the President. I just laughed and said 'Well, that's only cause I act like it. I boss everyone around.'. She laughed and so did one of the counsellor who was standing with me. But it hit me, that I had no idea how important my role in this calling was. And that the reason why I've made such a huge effort to do my best with it, it shows in my attitude toward the other leaders and the girls. I really enjoy my calling. I know what my calling is, and i'm doing exactly that. I don't overstep on anything, I take the minutes for all the meetings, i do the agenda for that meeting, i give out the assignments to everyone, do up the calendars, update all the records, take the rolls etc. But just typing everything up takes quite a bit of time. Even with my speed typing off 75wpm it still takes me at least a day to type everything up and emailed out to everyone, as well as printing them out to have a hardcopy of them. And then on top of that, I'm expected to help out with the activities as well if i'm needed. And with most of the combined activities, i am required to be there, either for transport or even just for support.
So my theory, at the end of all of this, is that, if you find something that you really enjoy, stick to it and you will be happy. espeically when you feel that life is going good for you. But to just enjoy it.
