profit blockers. We've got a set of skills that we go into business with. We might have learnt our skills at college, we might have been working under a plasterer for five years, six years, seven years. We might feel quite confident in skimming or whatever it is, maybe a bit of bonding coat, whatever it is. We go and work for ourselves and we've got a, at this point really it's a limited skill set that we've got and we go self-employed. But when we start having kids and buying houses or renting a house or buying a car, getting payments on bits and pieces, we get a little bit trapped in the way of, we need the money coming in now so we don't pay much attention to learning new skills. Because we need to just keep getting that working and keep working, you know, keep paying the bills so we can provide for our families, etc. So whether we make a decision or it's an unconscious decision, I think that we stop learning. So that for me is a big profit blocker. If we stop learning and we stop developing ourselves, whether that's on the tools or off the tools, if we stick with skill sets that are at risk of becoming obsolete and where people just don't want them anymore, the demand for them's disappearing and fading, we're at risk of our earnings sliding, we're at risk of not earning the money we could potentially earn. So making an unconscious decision, maybe it's not on purpose, but we're making a decision with our behaviours that we're going to stop learning and we're just going to focus on earning and getting the work in. So I think that's one of the profit blockers that happens to us. I see a lot of this happening on child talk and lads I'm working with on site, lads I see at the building, merchants and things like that. They've got a mindset that says I can't do it, a mindset that says, you know, I can't afford to go and learn silicon rendering or Venetian plastering or I'm not asked learning about corksault or EWI systems. It's too much hassle, it's too expensive, there's no demand for that near me. I'm just going to carry on and crack on with what I'm doing and what's always worked. That's dangerous way of thinking. So making a decision to stop learning is a profit blocker lads.
