Focus on a weakness related to your profession but not an essential job duty. For example, suppose you say your weakness is your interpersonal skills. In that case, the interviewer may pass you over for another candidate since that skill is an essential part of being an excellent Substance Abuse Social Worker.

"My greatest weakness is finding a work/life balance. I love my job and often take on overtime, which cuts into my family life. To find more balance, I started scheduling my family time as I would my work schedule. If I am asked to work overtime when I have scheduled family time, I politely decline. Making more time for my family has helped me relieve stress and keeps me more focused and energetic at work."
