He was rewarded for his impressive performances by being named the RBS Player of the Championship, the Welsh Rugby Writers Player of the Year and the Welsh Players' Player of the Year.
But the Newport Gwent Dragons man, who returned to action against London Irish last week, still fears for his position - at both club and country.
"I had a good year but I always worry for my position, even at the Dragons," said Lydiate.
"There's always pressure but you can only focus on yourself.
"It just makes me want to train harder, work on my weaknesses and keep improving on my strengths. There's plenty to work on, especially when there are guys pushing you all the time."
Lydiate became renowned for his knee-capping hits throughout last season and while he has vowed to continue his role as a defensive menace he is determined to improve on his all-round game.
"I'm really trying to develop an all-round game," added the 24-year-old.
"I want to make sure I'm not known for just one thing. If you get picked in the team you need to work on the things you're not so well known for.
"The chop-tackle is something that works well for me and is suited to my position but in another six months there might be a more effective way of tackling. You have to keep up to speed and keep evolving."
Lydiate is embarking on another massive season which could culminate in a call-up to the British Lions tour to Australia.
But while he admits it is a target he insists his sole focus is on life at Rodney Parade and their PRO12 kick-off against Italian new-boys Zebre on Friday.
"It's an exciting year with a lot of opportunities to play top quality opposition but I'm just keeping my head down," added Lydiate.
"I can only take each game as it comes but hopefully we can put a good run of form together at the Dragons leading up to the autumn internationals.
"The Lions is another goal and dream for me but with rugby and injuries you just don't know what will happen. I just hope that if I'm fit and playing well that I will be in with a chance.
"But all of that is last on the agenda. I have to make sure I am in good form at the Dragons. Last season we were not good enough but the boys have been working hard, pre-season has served its purpose and we're all looking forward to the new campaign."
