Motherwell are the 25-year-old's 13th club and he made an ideal early impression when he struck a swerving equaliser from more than 30 yards to earn the Lanarkshire side a 2-2 draw at Dundee United on his second appearance.
The Rotherham winger is on loan until January but wants to stay longer after settling in quickly.
"The last goal I scored was the start of last season so to get off the mark was brilliant," he said.
"I want to play every week. I just need to improve my fitness and show what I can do off the ball.
"I'm enjoying my time here immensely. I have only been here a few weeks but I have settled in nicely.
"The lads are brilliant, and the staff and everyone, I couldn't ask for a better group of people."
Ainsworth explained why he had gone out on loan nine times in his career.
"For the love of playing football, you don't just want to sit around and watch games go by," the former Watford and Huddersfield winger said.
"I have been bought a few times. I have been unfortunate with managers getting sacked but then again if you're good enough, you will play.
"But I have always known how good I am and I still know what I can do and what I can bring to Motherwell.
"It's a great place to be, a good league and a good manager and a good team, and that's what I want to be involved in."
Ainsworth's equaliser was no more than Motherwell deserved following an entertaining Scottish Premiership clash at Tannadice.
The visitors dominated before Henri Anier volleyed them in front on the half-hour mark but United hit back after the break with two goals in four minutes through Nadir Ciftci and Andrew Robertson.
Keith Lasley hit the inside of the post with a free-kick before his side equalised and both teams pressed for a winner.
Robertson's goal was also his first for his club as he continues to exceed expectations following his summer move from Queen's Park.
The 19-year-old left-back, who ran more than 60 yards unchallenged before firing home from long range, said: "I thought I could always make the step-up but I think I've probably made it quicker than I expected.
"But I knew I had it in me so luckily I have started off well."
