I hate to bring up this age topic again - sorry!
The concept that you have to be 25 to be an animator - is just absurd.
I think age has nothing to do with starting a career in animation. I do agree, that it’s most likely that you’ll see young folks in these types of positions - but I have a feeling that it has to do with the crazy deadlines, sometimes stressful situations and long productions hours that accompany such jobs. People who are older and have famlies, don’t want to have to dedicate thier lives to work; their priorities have shifted elsewhere. Of course, this isn’t true for everyone - there are alot of very successful animators who have families and an career in animation - it all depends on everyone’s indivudual goals, needs and wants - and being able to have a balance that works.
From my experience in a production environment - it at times is very demanding, requires long hours and working weekends. You have to really love what you do. Sometimes you’re really dragged throught the ringer.
Your portfolio also stands in front of your age when you’re applying for a job. The hiring manager is going to want to see your work first - the first thing that pops into thier head isn’t “How old are they?” I think that the older you are, the better - you’ve had more life experience and most likely - more career experience to back you up (regardless if that experience was in the field you currenly seek). Showing leadership, good job performance and determination can be seen in any type of job that you do.
If you love animation, and you want to be an animator…you’ll get there. Have patience, enjoy the ride, learn along the way. If you want something bad enough - you’ll get it, confidence, skill and perserverance rises above age.
