Adams was sacked just 22 games into the job as Pompey boss.
The 42-year-old insists he wanted more time and backing at the club.
“I am a little bit surprised, but results haven’t been good,” admitted Adams.
“I haven’t had a lot of time and I certainly haven’t had the financial backing. We’ve had a few injuries as well and that’s tough to take.
“It’s not turned me off management that’s for sure.
“I’ve just got to make sure I get all the parameters right before I walk into the next one.
“I can’t wait to get back in and have another bash. But I won’t be impulsive, I’ve got to learn from that and make sure I get things right.”
