Once you know how much your dream will cost, it's quite simple to break down how you're going to get the money together.
The further ahead you plan, the easier it is too, so it's never too early to start. You can set a monthly savings target and examine additional options, such as overtime or selling something of material value to meet your budget.
Don't forget that for trips that involve more than just you – other people should be contributing too, that includes teenagers who can be expected to save for airfares, etc.
Ask yourself: How long can you plan ahead for?
