How to write my CV as a bit of a job hopper?

I'm 20, and I've had a fair few jobs in my almost 5 years of working. 7 to date. It's not that I can't hack it or get bored, they've all been for good reasons.

First job I held almost 2 years, but moved because of a change in management, it was also ages from my house. Second I held for 6/7 months until Feb of y13, and left to focus on a-level exams, couldn't get that one back in summer as they'd obviously replaced me so found a summer job in a kitchen. Was independent so couldn't transfer, and had to get a new job at uni, which was zero hours, and after a few months I realised I needed more hours than they could give so I quit and got a new job after Christmas. Kept that until summer, it was also independent so couldn't transfer, got a summer job in a pub this summer. Upon returning to uni, my old job would've taken me back, but I found another paying an extra £1.50 an hour with no late finishes. However, I've worked here since august and other problems have emerged, and I would rather not return after Christmas, so I'm job hunting again.

I like to include as much as I can on my CV as it's quite versatile. 1 job was a supermarket, 1 was retail, 1 was in a kitchen, 1 was as a barista, 1 was as a waiter and the other 2 were bar work. So it shows a variety of skills. But it is just silly to include them all at this point. My last time applying for jobs I was just omitting the less relevant ones, and explaining the gaps if it came up, but I'm less sure now on what to include and what not to. For example, most jobs in my area are bar/restaurant, so it makes sense to omit the supermarket, but that was my longest job, almost 2 years, so if you take that out it looks like I've never stayed anywhere longer than a few months.

Any advice would be much appreciated
