If you think about it, our planets were made from the ashes of a nebula, which is a dead star. But that took hundreds of years. Will our sun burn out too, or do I just need to find a hobby?

That’s only true to the current outer layer of the sun.
Now consider that the sun will expand from its current ~1.4Mkm diameter to anywhere between 1.2 to 2 AU (1 AU being the distance between the sun and the Earth on average, so about 150Mkm). That’s a 200 times increase in radius/diameter, resulting in a drop of the surface temperature to around 2400K, which, while isn’t ideal for life (and in fact arguably the coronal plasma itself would be a bigger issue for life et al), is also not something the planet couldn’t withstand for a good while. After all we’re talking about a measly 2000 degrees Celsius or so.
