The Eagles got the jump in Sunday's derby to lead by four goals during the second quarter, but things then quickly fell away, with Fremantle romping to a 38-point victory.
While the skill level and pressure over a full game needs to improve, Selwood wants to focus on some positives, which included his brother Scott's job on Stephen Hill and the form of Brad Ebert and Tom Swift.
"We'll focus on both the positive and negatives, but you have to focus more on the positives because that shows that you are capable of actually doing it. If you show all the negatives, then everyone thinks it's all doom and gloom," Selwood said.
"We'll look more at the positives, but obviously there were areas we did get exposed in and we have to try to fix them up for next week. Hawthorn will be studying that game to do the same thing to us.
"We are in the exact same position as them. They will be expecting the exact same from us, and we just have to be ruthless and cut-throat to hit them early and get the momentum."
After leading by 23 points at the eight-minute mark of the second quarter, West Coast didn’t kick its ninth goal until the 21-minute mark of the last term, when Josh Kennedy broke the drought with two in as many minutes.
Selwood felt that the Eagles didn't cope well with Fremantle's pressure as the game progressed.
"They just brought a bit more pressure, got some momentum and our skill errors crept in again," he said.
"We were up and about early (putting) a lot of pressure on them and moving the ball quickly, but we got caught out, and it's hard to get that back once we lose it.
"Fremantle are a good side and they bring that pressure football. We've got to get exposed to that if we want to head to finals football one day. As long as we keep learning, who knows - it might turnaround next week, or it might be a bit later. We have to keep positive."
