"I still feel motivated, I have ambition, I still want to do it," Lewandowski said at a news conference in Warsaw on Tuesday.
If he plays in Friday's Nations League match against Bosnia and Herzegovina in Warsaw, it will be his first appearance for Poland since joining Chicago Fire and his 168th international appearance.
Lewandowski said he still has not decided when he will end his international career.
"I sometimes ask myself these questions. After 18 years of playing for the national team, after leaving my heart here, after all the pain and everything that comes with it, I won't be able to answer that question until I decide that this is the moment," he said.
"I can make plans, but you know very well that when I make a decision, it has to be very carefully considered. And it won’t be an easy decision because it’s also a matter of the heart," he added.
The 38-year-old forward said he was not yet feeling the effects of his long journey from the United States to join Poland’s training camp, which began on Monday in Warsaw.
"I’m ready to play. In what capacity, it's hard to say. We’ll probably be able to discuss it more from day to day and make decisions," Lewandowski said. "As long as I can and have the strength, I’m absolutely available to the coach."
Lewandowski said soccer in Chicago, as well as in Major League Soccer generally, differs from the game in Europe.
Without giving specific examples, he said people in the United States pay attention to aspects of the sport that are rarely discussed in Europe. He said the experience had given him a new perspective that he particularly valued at this stage of his career.
He also highlighted lessons beyond the sporting side of the game.
"I've always approached soccer as more than just a sport. I've also thought about what it would give me as a person and what I could use in other areas," he said.
Friday's match against Bosnia and Herzegovina will open Poland's campaign in Group 4 of Nations League B. Poland played in the top-tier League A in the competition's previous four editions.
Poland will travel to face Sweden three days later, host Romania in Warsaw on October 2 and play Bosnia and Herzegovina away on October 5.
"I think these are teams at our level," Lewandowski said. "The fact that we previously played in League A was above our level, and there's no point fooling ourselves about that."
He also pointed to the demanding schedule, with four matches to be played in a short period.
"It's a difficult schedule, the first time we've had four games in such a short period. For many national teams, it's a question of how to get through this camp and how to manage playing time," he said.
"It’s a challenge, but I hope we can handle it and that it will be visible on the field that we're not only playing good soccer, but also winning and collecting points in the Nations League," Lewandowski said.
Poland will conclude the group stage in November with an away match against Romania and a home game against Sweden.
To return to the top division, Poland must finish first in Group B4 or finish second and then win a playoff against a team from League A.
