Start small, plan for success and keep smiling. There's no end of good information about adventure travel. You can start at the library or check out your local magazine stand. Also, talk to friends. Jump on the Internet.
Many sites offer free online counseling.
Don't overestimate your abilities when you choose an adventure. A little risk feels good, but too much danger can easily spoil your good time. Don't be suckered into an adventure by pretty pictures. Put yourself in the picture. Think about it.
