Taking on board what MissNine said, I think your Mum's messages can be intended and translated as being quite concrete in nature. I'm feeling that your Mum is lovingly making certain opportunities available to you, which you keep overlooking... Serendipity type stuff.
Serendipity is a huge one for me, and is a big part of that trust I mentioned earlier. There may be things that pop up along your path that intrigue you, opportunities which attract your attention, but which you keep blocking, saying things like "If only I had more time, money etc" as an excuse to delay such things, rather than being creative in finding a way to make them happen... That is my feeling, and, again, it relies on trust.
