Excellent advice.
A successful climb is one in which you return from. It will take some time to find someone you click with where you both can bring something to the table. One that can push yourself beyond your perceived limits safely. The mountains will always be there.
Hit the crags, gyms, take some classes join a club, go on a hike w/ someone from a mssg board..whatever. You never know who'll you'll meet and what they have to offer. Baddasses come in all shapes, sizes and ages.
