No.
The general
rule is: Educational expenses to improve your current job skills are deductible.
But learning a new job is not. From JK Lasser’s Your Income Tax 2013, pg 580:
"For a deduction, the courses must be related to your existing job
responsibilities and not lead to qualification for a new business.
But
if you took this course, for credit, at a college, (unlikely for a yoga class) it may count for the tuition
deduction or credit. You must be a degree candidate to get the American
Opportunity credit. But, you can get the tuition adjustment (above the
line deduction) or Lifetime learning Credit by just being a high
school grad (or have a GED) enrolled in a qualified school. Expenses that qualify
for an education credit or Tuition & Fees deduction are qualified tuition
and related fees required for enrollment or attendance at an eligible
educational institution. An eligible educational institution includes most
accredited colleges, universities, vocational schools, or other post-secondary
educational institutions eligible to participate in the student aid programs
administered by the Department of Education. The educational institution should
be able to tell you if it is an eligible educational institution.
