Ex-presidents of the United States (US) often go on to do a wide range of things. Jimmy Carter contributed to humanitarian causes while George W Bush picked up a paintbrush. But Donald Trump has never been a traditional politician so there is no reason to think that he will act like other former presidents.
So, what can he do? Here are some of the possibilities.
He could run again
Losing against Joe Biden in a close election doesn't have to be the end of Mr Trump's career. The US Constitution stipulates that, "No person shall be elected to the office of the President more than twice," but there's nothing about terms needing to be consecutive, reported the BBC.
And Mr Trump may seek to do just that.
Donald Trump loves campaign rallies and he received 71.5 million votes in the election - a record total for a losing candidate and one that demonstrates a significant base of support among the US public.
Rescue his business empire
Mr Trump was a real estate mogul before he became a politician. He might want to pick up where he left off four years ago and get back into the world of business, the BBC added.
The New York Times has reported that Mr Trump has over $400m (£300m) in loans coming due over the next few years – though he has said that represents "a tiny percentage" of his net worth.
The Trump Organization has numerous hotels and golf courses. There are Trump-branded properties in Mumbai, Istanbul and the Philippines – and of course, Washington, DC – and golf courses in the US, the UK, Dubai, and Indonesia, many of which being in the travel and leisure industry, have been badly affected by the pandemic.
Forbes has reported his wealth could have taken as much as a $1bn hit due to Covid-19.
So, if he wants to focus on this particular course, he sure has plenty of work ahead of him.
Become a media magnate
President Trump is no stranger to television so there is a lot of speculation that his ambition is to get involved in the news media, either by launching his own channel or collaborating with an established conservative network.
Trump might also choose to fall back on the controversy – which he thrives on.
Presidents often sign book deals, with Barack and Michelle Obama netting a record-breaking joint deal reportedly worth $65m – though that amount is rare. George W Bush got a rumoured $10m advance for his memoir.
Leaving his job as the president, Mr Trump will have a presidential pension – and plenty of other perks. The Former Presidents Act, enacted in 1958 to "maintain the dignity" of the office, provides benefits including an annual pension, which was $207,800 (£158,124) in 2017.
Former presidents are also eligible for lifetime Secret Service protection, health benefits, and travel office and staff expenses. So Mr Trump, now 74, could decide to quietly retire.
But is Donald Trump a personality you see fading away like that? A question that feels even more ridiculous to ask but, we will have to wait and see.
Maybe after four years of presidency, Mr Trump might fancy some spare time relaxing and playing golf in Florida at Mar-a-Lago, his Palm Beach retreat.
