Don't cut it off, seriously!! I have had loooong hair for years and decided I wanted a change - I cut it off and now instead of taking 5 seconds to scrape up into a messy bun/ponytail when I'm pressed for time, I have to stuff around with straighteners and styling products for ages and usually get frustrated and end up scraping it back into a messy bun anyway!

Keep it long, and maybe opt for a change of colour, get a blunt fringe (a longish one is flattering on nearly all face shapes!), throw some layers in... different doesn't necessarily have to mean 'the chop'!
