Since graduating from college in 1991 with BA psychology, I have obtained these certifications and tools:
1) A+ and several years of experience
2) MCSE certification and experience
3) CDL class A license with over 500,000 miles
4) Forklift certification—amazingly many employers request this if in logistics
5) Several certifications on alcohol serving and culinary arts(I own part of a restaurant/bar)
Education never ends and one should be always updating their skills.
Next—learning Spanish!!
