SMART is an acronym used to describe detailed and results-oriented objectives.
SMART goals are:
Specific — they say exactly what they want to accomplish
Measurable — they can be measured in units
Achievable — you can complete them without burning yourself out
Relevant — they support what you do
Time-bound — you specify when you'll complete them
So a vague career goal would be 'I'm going to learn JavaScript.'
But a SMART goal might look like this:
'I'm going to achieve proficiency in Python within the next six months by dedicating at least 10 hours per week to an online Python boot camp course and applying basic formulas to the functions of my current job.'
