Any tips for climbing with A rope that is to short?

I have two 30 meter rope and mostly stick to the same single pitch climbs that are bolted for 30 meter ropes. But as I grew in skill I wanted to branch out to other climbing areas, but most other locations in my area are bolted for 40 meter ropes. What should I do? is there a trick I can use or do I just need to bite the bullet and buy a 60 meter rope?

Buy a seventy meter, ten millimeter, dynamic rope and give yourself some breathing room. After you have worked the ends for a while, cut it down to a sixty meter and freshen up the ends for more hard use. Finally when it is feeling a little beat, cut it in half and you have two more ropes for the small rocks. At this point buy another new seventy meter rope.
