Commitments (time & money), priorities, other interests, disposable income, travel / transport
If you can get these balanced then you can play.
In a persons life their ability to have disposable income varies.
A 'child/youth' can have income from parents, part time jobs etc. As long as they are not destitute then the majority or all of this is disposable income.
(The 'supported' youth has their accommodation and food available, and does not have commitments to support others, and can target one interest if they like)
They can commit to paintball while they have the financial support (job or parent money), free time (part time jobs, homework, course work & exam preparation heavily eats into this), and transport.
Youngsters tend to go all or nothing, and will commit to paintball 100% while they can, or until they go onto the next hobby.
An 'older youth' gets less support handed to them from family and get pointed towards jobs (or as they get older the applicable minimum wage and legal working hours rise) This results in a bigger disposable income, but can also coincide with the potential of independant travel - a moped, car etc. They may get their own transport, or just a licence and get named on the insurance of the family car. (Or one of their friends does)
Independant transport is a double edged sword - it opens up freedom but costs money.
They can commit to paintball if they have the money, time and transport. These will dry up at times, but they can drop in out of paintball
Then later in life a person establishes themselves with a regular job. They have commitments - even if they don't have a family they still need accommodation, food, and unless they live where they work - transport.
The schoolchild is in danger of going for all or nothing - discovering paintball, buying everything, then losing the balance of all the factors and ending up moving on
If you cannot play at the moment then consider hanging on to all or some if your gear - even just goggles mean you can rent a gun and have the right goggles for you.
The difficulties of time will change, and if you've still got the gear it will be easier to drop back in
But if it realy has got in your blood then don't worry - you will get back one day
